From: Helge Deller <del...@gmx.de> There were some regressions introduced with Qemu v8.2 on the hppa/hppa64 target, e.g.:
- 32-bit HP-UX crashes on B160L (32-bit) machine - NetBSD boot failure due to power button in page zero - NetBSD FPU detection failure - OpenBSD 7.4 boot failure This patch series fixes those known regressions and additionally: - allows usage of the max. 3840MB of memory (instead of 3GB), - adds support for the qemu --nodefaults option (to debug other devices) This patch set will not fix those known (non-regression) bugs: - HP-UX and NetBSD still fail to boot on the new 64-bit C3700 machine - Linux kernel will still fail to boot on C3700 as long as kernel modules are used. The whole series can be pulled from the "hppa-fixes-8.2" branch from: https://github.com/hdeller/qemu-hppa.git hppa-fixes-8.2 SeaBIOS v15 has not changed in v3, so it is not included in this patch review series but will be added in final pull request. Please review. Changes v2->v3: - Added comment about Figures H-10 and H-11 in the parisc2.0 spec in patch which calculate PDC address translation if PSW.W=0 - Introduce and use hppa_set_ior_and_isr() - Use drive_get_max_bus(IF_SCSI), nd_table[] and serial_hd() to check if default devices should be created - Added Tested-by and Reviewed-by tags Changes v1->v2: - fix OpenBSD boot with SeaBIOS v15 instead of v14 - commit message enhancements suggested by BALATON Zoltan - use uint64_t for ram_max in patch #1 Helge Deller (9): hw/hppa/machine: Allow up to 3840 MB total memory hw/hppa/machine: Disable default devices with --nodefaults option hw/pci-host/astro: Add missing astro & elroy registers for NetBSD target/hppa: Fix PDC address translation on PA2.0 with PSW.W=0 hw/hppa: Move software power button address back into PDC target/hppa: Avoid accessing %gr0 when raising exception target/hppa: Export function hppa_set_ior_and_isr() target/hppa: Fix IOR and ISR on unaligned access trap target/hppa: Fix IOR and ISR on error in probe hw/hppa/machine.c | 28 +++++++++++++++++----------- hw/pci-host/astro.c | 26 +++++++++++++++++++++++--- target/hppa/cpu.c | 6 +----- target/hppa/cpu.h | 1 + target/hppa/mem_helper.c | 27 ++++++++++++++------------- target/hppa/op_helper.c | 6 +----- 6 files changed, 57 insertions(+), 37 deletions(-) -- 2.43.0
